The literature on the treatment choice problem has become an area of active research since the pioneering works of [1]}, [2]}, [3]} and [4]} introduced a decision theoretic framework to the problem. Minimax regret treatment choice rules for finite samples are derived in [5]} and [6]}. [7]} considers asymmetric regret criteria. Treatment choice analysis given partially identified welfare includes [1]}, [9]}, [10]}, [11]}, [12]}, and [13]}. [14]} investigates a Bayesian approach to treatment choice, and [11]} and [16]} discuss a robust Bayesian approach.
